BRIDGING FOR J OISTS.

Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed July 8, 1916. Serial N 0. 108,104.

To all whom it may concern Be it known that I, EDGAR K. DAY, a citizen of the United States of' America, and resident of Wheeling, county of Ohio, and State of West Virginia, have invented certain new and useful Improvements in Bridging for Joists, of which the following is a specification.

This invention relates to bridging for joists, and it has for its primary object to provide a simple, inexpensive and strong brace or bridging composed wholly of sheetmetal.

A further object of the invention is to provide companion bridging members of sheet-metal, said members being permanently united and adapted to be disposed in crossed relation.

With these and other objects in view, the invention. resides in the features of construction which will hereinafter be fully described, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a plurality of joists, showing my invention applied thereto; Fig. 2 is an enlarged plan view of a sheet-metal blank cut and ready for forming; Fig. 3 is a similar view of the shaped members; Fig. 4 is a perspective view of the invention, the members being shown in crossed relation, as when applied to adjacent joists; and Fig. 5 is an enlarged section on line 5-5, Fig. 4.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views-1 and 2 indicate bridging memberscotnposed of sheetmetal and each of which is substantially V-shaped in cross section, as shown in Fig. 5. Said members are adapted to be disposed in crossed relation and to be mounted in inclined cross-bracing position with respect to adj acent joists 3 of a building structure, each of said members having its opposite ends 4 fiat in form and inclined at an angle to the axis of its body so that they are adapted to seat for attachment upon the opposing faces of adjacent joists at points adjacent to the upper and lower edges, respectively, of the thus left which connects the two parts of the blank, which parts are then shaped to form the two members 1 and 2 which are then per-v mitted to remain in parallel relation, as shown in Fig. 3, until such time as they are to be applied for use, when they are relatively turned to occupy substantially the positions shown in Fig. 4. As is obvious, the tie 6 serves to retain the members in their proper relation when the last-mentioned positions are assumed.

What is claimed is- 1. A bridging composed of a single sheetmetal' blank and consisting of a pair of similarly shaped brace members formed by two longitudinally disposed incisions produced at opposite sides of the median line of the blank and extending from opposite ends to points slightly past the middle of said blank, to leave a slender unseveredportion whereby said members are permanently connected, said members being adapted for turning into relatively crossed relation.

2. A bridging for joists consisting of a pair of similarly shaped brace members out from a single sheet-metal blank, said members being disposed edge to edge in parallel alinement, and a slender unsevered integral connecting tie disposed intermediate said members substantially midway between their ends, said members being adapted to be disposed in relatively crossed position with said tie maintaining their closely associated relation.

In testimony whereof, I aflix my signature in presence of two subscribing witnesses.
